How much structure do people actually want when they build thinking systems?

I spend a lot of time working on cognitive systems — environments that give people a stable core while still leaving space for their own way of thinking.

Something I keep noticing: people approach structure very differently.
Some want small pieces they can shape themselves.
Others prefer clear routes that already exist.
Some want full freedom inside a defined zone.
Others want a ready‑made function that simply works.

I’m trying to understand this more precisely.
When people use a system that supports thinking or reasoning flows, what do they actually look for — a flexible base they define themselves, or a complete structure they can rely on?
